Dirt and Antibiotics

From the BBC:
Soil is teeming with millions of different micro-organisms that produce lots of potentially therapeutic compounds, including new antibiotics. Dr Sean Brady's team at New York's Rockefeller University has been busy unearthing them. They used a gene sequencing technique to analyse more than 1,000 soil samples taken from across the US. When they discovered malacidins in many of the samples, they had a hunch it was an important find. They tested the compound on rats that they had given MRSA and it eliminated the infection in skin wounds. The researchers are now working to improve the drug's effectiveness in the hope that it can be developed into a real treatment for people.

Dr Brady said: "It is impossible to say when, or even if, an early stage antibiotic discovery like the malacidins will proceed to the clinic. "It is a long, arduous road from the initial discovery of an antibiotic to a clinically used entity." (Read more.)
